Democrat Eileen Laubacher unseated Republican Lauren Boebert in Colorado’s 4th District on Friday, according to a race call by The Associated Press.
Laubacher, a retired Navy rear admiral, led with 48.8 percent of the vote to Boebert’s 47.9 percent, maintaining a margin of 3,441 votes, Roll Call reported.
The loss changes the region's political makeup, as the 4th District—a territory spanning eastern Colorado—was unexpectedly competitive this cycle. While the district was traditionally viewed as a stronghold for the GOP, the results suggest Democrats are finding ways to compete even in deep-red areas.
The election results contribute to a trend in the state, where Democrats have secured all of Colorado's House seats with the exception of the 3rd District, held by Rep. Jeff Hurd.
Boebert’s move to the 4th District was a strategic attempt to find safer ground. She previously represented the 3rd District, centered around Colorado’s rural Western Slope, where she narrowly won a 2022 reelection bid against Democrat Adam Frisch. The New York Times said that Boebert switched to the 4th District after Frisch announced his intention to run again in 2024.
The 4th District was widely considered much friendlier terrain for Republicans, yet the outcome suggests that Boebert’s brand of disruption did not resonate as expected in this new constituency. Her campaign lacked sufficient funds throughout the race.
| Candidate | Campaign Funds (as of mid-October) |
|---|---|
| Eileen Laubacher | $13.7 million |
| Lauren Boebert | $1.2 million |
Laubacher proved to be a formidable fundraiser, bringing in more than ten times the capital of her opponent by mid-October.

Since her 2020 upset primary victory over five-term incumbent Scott Tipton, Boebert has been one of the most prominent and polarizing figures in the House GOP conference. She established herself as a disruptor through high-profile confrontations, including heckling President Joe Biden during his 2022 State of the Union address and public disputes with former Rep. Marjorie Taylor Greene.
Her tenure was not without personal controversy. In 2023, she was involved in an incident at a Denver theater that was documented on surveillance video, an event that led to a subsequent apology tour.
Even her political alliances faced volatility. Although she held Donald Trump’s endorsement, her relationship with the former president experienced tension after she advocated for the release of files related to Jeffrey Epstein.
The outcome in Colorado questions whether moving candidates between districts to avoid competitive matchups is effective. It is unclear whether the Democratic surge in Colorado is a temporary realignment or a permanent change in the state's political geography.
